Don’t approve of combined scanner/printers. One bit fails it usualy all fails.

My current scanner is USB, came from a computer fair last year and was £37. Week after it was £35 – bugger. Works perfectly, actual resolution 600dpi I think.
If it was only for displaying on forums and the like, buy the cheapest you can get as monitors only show 72dpi anyway.

If you really want to scan negs and slides, wait and save up a bit more. Saw an Epson Perfection 3200 or similar advertised recently. Resolution 3200 x 6400, built in slide/neg capability, scans 12 35mm slides in one hit, about £260. Could be + VAT, sorry, as I’m VAT registered I tend to not take a lot of notice.
That’s substantially higher resolution than a dedicated Minolta slide scanner a mate bought a year or so ago.
